2. Nominal Pipe Size - Wikipedia

   en.wikipedia.org/wiki/Nominal_Pipe_Size

   Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. [1] " Nominal" refers to pipe in non-specific terms and identifies the diameter of the hole with a non-dimensional number (for example – 2-inch nominal steel pipe" consists of many varieties of steel pipe with the only criterion being a 2.375-inch (60.3 mm) outside ...

3. Electrical conduit - Wikipedia

   en.wikipedia.org/wiki/Electrical_conduit

   It is a new type of plastic wire conduit in the industry. Compared with PVC electrical conduit, it has three advantages. First: low smoke. Due to the unique material and formula, LSZH conduit only produces a small amount of black smoke when burning, and most compounds will absorb heat energy and release steam when burning.

4. National pipe thread - Wikipedia

   en.wikipedia.org/wiki/National_pipe_thread

   The standard for Nominal Pipe Size (often abbreviated NPS, which should not be confused with the abbreviation NPS for the straight thread form standard) is loosely related to the inside diameter of Schedule 40 series of sizes. Because of the pipe wall thickness of Schedule pipe, the actual diameter of the NPT threads is larger than the Nominal ...

5. Pipe (fluid conveyance) - Wikipedia

   en.wikipedia.org/wiki/Pipe_(fluid_conveyance)

   Steel pipe has been produced for about 150 years. The pipe sizes that are in use today in PVC and galvanized were originally designed years ago for steel pipe. The number system, like Sch 40, 80, 160, were set long ago and seem a little odd. For example, Sch 20 pipe is even thinner than Sch 40, but same OD.

6. British Standard Pipe - Wikipedia

   en.wikipedia.org/wiki/British_Standard_Pipe

   These standard pipe threads are formally referred to by the following sequence of blocks: the words, Pipe thread, the document number of the standard (e.g., ISO 7 or EN 10226) the symbol for the pipe thread type: G, external and internal parallel (ISO 228) R, external taper (ISO 7) Rp, internal parallel (ISO 7/1) Rc, internal taper (ISO 7)

7. Heat transfer coefficient - Wikipedia

   en.wikipedia.org/wiki/Heat_transfer_coefficient

   For a fluid flowing in a straight circular pipe with a Reynolds number between 10,000 and 120,000 (in the turbulent pipe flow range), when the fluid's Prandtl number is between 0.7 and 120, for a location far from the pipe entrance (more than 10 pipe diameters; more than 50 diameters according to many authors [10]) or other flow disturbances ...
